摘要 证明了一类抛物型方程组正解的存在性,通过迭代得到解的上、下界估计,这种估计依赖于一个预先给定的方程。 In this paper, we have demonstrated a parabolic system and derived the existence of its positive solutions and the iterative estimate of bound by using solutions of elliptic systems as uppersolutions or low- ersolutions. This kind of estimation is determined by one equation pregiven.
